MASCHINE UND VERFAHREN ZUM STABILISIEREN EINES GLEISES
The invention relates to a machine for stabilising a track, having a machine frame supported on rail-based running gears and at least one height-adjustable stabilising unit which can be rolled on rails of the track by means of work unit rollers, comprising a vibration exciter with rotating unbalanced masses for generating an impact force acting dynamically in a track plane normal to a longitudinal direction of the track as well as a linear drive for generating a load acting on the track. It is provided that a main unbalanced mass and a secondary unbalanced mass produce different centrifugal forces at the same rotational speed depending on the direction of rotation, the two unbalanced masses being coupled in such a way that, during rotation in one direction of rotation, the unbalanced masses have a first phase shift in relation to one another and that, during rotation in the opposite direction of rotation, the unbalanced masses have a second phase shift relative to one another which differs from the first phase shift. Depending on the arrangement of the unbalanced masses, a changed phase shift changes both the direction and the strength of the impact force.
